Rolling type double-surface projection curtain

Abstract

A rolling type double-surface projection curtain relates to a curtain which is a peripheral product of projector technology. The rolling type double-surface projection curtain comprises a tubular motor, a curtain, a curtain vertical shaft, an electric control box and a power plug. The tubular motor is covered in a pi-shaped cover. The curtain is a closed-loop-shaped double-surface curtain. The upper end of the curtain is packaged on the tubular motor, and the lower end is packaged on the curtain vertical shaft. The curtain performs closed-loop operation. The rolling type double-surface projection curtain is advantageous in that rolling operation of the closed-loop double-surface curtain is performed; each curtain displays a picture with a certain proportion; and the double-surface curtaincan display the pictures with two proportions. The double-surface curtain can be made of one or two materials. The rolling type double-surface projection curtain can perform functions of satisfying different-proportion displaying of a majority of video sources, realizing full-screen displaying and no black side, improving video effect, making viewing by the persons more comfortable, and realizingbetter three-dimensional frame. When the double-surface curtain is made of two materials, not only can a requirement for 2D film displaying be satisfied, but also a requirement for 3D film displayingcan be satisfied. The rolling type double-surface projection curtain well settles defects in prior art in a most convenient and economic method.

Description

Technical field: [0001] The present invention relates to the technology of projectors, mainly relates to screens of peripheral products of projectors, in particular to a rolling double-sided projection screen with different frame specifications and different materials. Background technique: [0002] Now, projectors have begun to enter thousands of households. There are various aspect ratios of the picture displayed by the projector, and the mainstream ratios are 16:9, 4:3, 2.35:1 and so on. However, the existing projector screens have a fixed display ratio, that is, a screen with a display ratio can only display a video with a ratio on the full screen. For example, the original black border of the screen has a width-to-height ratio of 16:9, and only a video with a ratio of 16:9 can be displayed on the full screen, so that people can get the best and most satisfying visual effect. If the screen of 16:9 video frame 15 is used to display the picture of 2.35:1 video, then ther...

Problems solved by technology

[0003] Another problem is about the material of the curtain. Existing curtains include fiberglass curtains, white plastic curtains, metal curtains, etc. A curtain can only be made of a certain material, and curtains of different materials are only suitable for displaying a certain For example, when a projector displays 2D images, the glass fiber screen is the best, and when the projector displays 3D images, the metal screen is the best. One screen cannot be suitable for both 2D and 3D display. There are also restrictions on different screen displays
